Select the set in which the numbers are related in the same way as are the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding / deleting / multiplying etc., to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (5, 80, 16) (18, 108, 6)
(13, 91, 7)
✅ Answer: Option 3 — (13, 91, 7)
Explanation:
We are given two sets of numbers:
(5, 80, 16)
(18, 108, 6)
Let’s denote each set as (A, B, C)
We are to find a logic or formula that connects A, B, and C.
Step 1: Check the relationship in each set
For (5, 80, 16):
Check if:
A × C = B
→ 5 × 16 = 80 ✅
For (18, 108, 6):
→ 18 × 6 = 108 ✅
So the rule is:
First number × Third number = Middle number
i.e., A × C = B
Step 2: Apply this rule to each option:
🔹 Option 1: (15, 185, 14)
→ 15 × 14 = 210 ≠ 185 ❌
🔹 Option 2: (17, 8, 135)
→ 17 × 135 = 2295 ≠ 8 ❌
🔹 Option 3: (13, 91, 7)
→ 13 × 7 = 91 ✅
✔️ This matches the rule.
🔹 Option 4: (9, 81, 8)
→ 9 × 8 = 72 ≠ 81 ❌
✅ Therefore, only Option 3 — (13, 91, 7) correctly follows the same pattern:
First number × Third number = Middle number
✅ Final Answer: Option 3 — (13, 91, 7)
